actually, the 97 which mine is, stock size is not like the 92-96 on a 97 stock size is
215/55/16 -1997 stock size
whereas a 1992 the stock size is 225/50/16
so going to 215/60/16 is according to Miata Calc
215/55-16 4.7in 12.7in 25.3in 79.5in 797 0.0%
215/60-16 5.1in 13.1in 26.2in 82.2in 771 3.3%
just trying to make the point, the 97 had its own stock size… as seen here on my VIN plate pic:
so my original Diameter is 25.3, going to a 26.2
anyhow here is the lugs just got, and a wheels pic, and a mounted tire pic, not installed yet…too cold out 11F now
a little luck, this will all work out. also still waiting on the centering rings, even though they are not really needed..
my poor SVX from FL, saw actual temp this morning on my drive in to work, of -5F on the climate control panel outside temp select….
and a taller tire will give better MPG right
